HUB.

SPECIFICATION forming part of Letters Patent No. 249,358, dated November8, 1881.

\ Application filed September 19, 1881. (No model.)

To all whom it may concern:

Be it known that I, JOHN A.HUDGENS, of Pine Bluff, in the county ofJefferson and State of Arkansas, have invented a new and usefulImprovement in Wagon-Hubs; and I do hereby declare that the following isa full, clear,

. and exact description of the same, reference beinghad totheaccompanying drawings, forming part of this specification, in whichFigure l is a vertical central section. Fig. 2

I is a sectional view on line as m, Fig. 1.

My invention relates to improvements in wagon-hubs; and it consists inthe peculiar construction and arrangement of the parts, as hereinaftermore fully set forth.

In the accompanying drawings, it represents a tapering metallicaxle-box, provided with a" circular shoulder, 11, near its inner end,against which the inner hub-collar abuts when the wheel is put together.That portion of the periphery of the axle-box lettered c d, lyingbetween the circular shoulderb and thenut, hereinafter described,whichreceives the hubvcollars or flanges and spokes, is made polygonalin form, and the remaining outer portion of the axle-box is madecylindrical, and screw-threaded on its outer surface, as shown at e.

It represents the inner, and h the outer, huhcollar, each of which isprovided with a central orifice the periphery ofwhich is of the samepolygonal form as the polygonal part of the axle-box, so that thehub-collars can readily be slipped lengthwise on the-axle-box and beprespokes Z, having the lower parts of their sides tapering, are thenplaced against the outer face of the inner collar, the ends of thespokes beinglsquared and resting against the polygonal faces of theaxle-box. The outer hub-collar is then slid on the axle-box and the nutscrewed on the outer end of the box, thus firmly securing the spokesbetween the hub-collars.

It will be perceived that in my construction I dispense entirely withthe employment of mortises and tenons, and that the hub-collars areprevented from turning, and that the construction is extremely simpleand cheap.

I am aware that a hub consisting of a hollow cylinder having a circularbeveled or con-' cave clampingdisk cast with it, and adapted to clamp aseries of spokes having enlarged inner ends, in conjunction with anotherflange screwed on the hollow cylinder, has heretofore been employed; andI therefore lay no claim to such construction, my invention beingconfined to the construction of parts pointed out in the claim, wherebythe inner collar is separate from the axle-box, so that if a collar isbroken it may be replaced without the necessity of providin g for a newaxle-box, and neither collar is screw-threaded around its'centralorifice.

I claim as my invention The combination, with the taperingaxle-box a,provided with the circular shoulder b,po1ygonal portion 0 d, andcylindrical outer end, 6, screw-threaded on its periphery, of thehubcollars h h, having polygonal central orifices, nut 7c, and spokes I,having their squared ends resting against the polygonal faces of theaxlebox, and'having their front faces beveled inwardly and abuttingagainst each ether, and their side faces straight and abutting againstthe collars, substantially as described, and for the purpose set forth.I
